Spark proves to be an unnaturally strong and gifted child. He takes to his training well, and advances from an early age. He excels at fighting and defense, and becomes abnormally strong, fast, and agile almost immediately. Then one night, as the two are practicing under the stars, they notice a bright light explode in the sky. They run up the mountain to see where this object landed and find a space pod. Within it is a young child, Ace, alone and vulnerable. Master Zo takes him back to his cabin and raises him alongside Spark. The two become brothers. Their bond becomes even stronger when they are each infused with powerful shards that fell from space once they become young adults. These energy shards give them supernatural abilities and change their lives forever.
